The two teams meet again Tuesday night in Boston.

The Senators led 2-1 after 40 minutes despite being outshot 31-17. Anderson was perfect in the third period, and Stone sealed the victory with an empty-net goal with 54 seconds remaining.

Boston tied the game at the 7-minute mark of the second after a video review showed Krejci's shot from in close had fully crossed the line.

Ottawa regained the lead late in the period when Zibanejad jumped on the rebound of Bobby Ryan's shot.

The Bruins played well early. At one point, Boston was outshooting the Senators 16-6, but Ottawa still opened the scoring.

The Senators took advantage of a power play when Stone, behind the net, banked a shot in off Dennis Seidenberg's skate in the final seconds of the period.
